This study is the first administration of GSK2890457 in humans. The study will be conducted in 3 parts: - Part A (conducted at a single investigative site) will determine the safety and tolerability of GSK2890457 alone in healthy subjects during six weeks of dosing, as well as evaluating the potential for a pharmacokinetic interaction with metformin. Part A consists of Screening, Treatment (6 weeks) and Follow-up periods. - Part B (conducted at multiple sites) will determine safety, tolerability, and pharmacodynamics (PD) in subjects with Type 2 diabetes (T2D) when co-dosed for six weeks with liraglutide (Victoza). Part B consists of Screening, Run-in (1 week), Stabilization (12 weeks), Treatment (6 weeks) and Follow-up periods. - Part C (conducted at multiple sites) will determine safety, tolerability, and PD in subjects with T2D when co-dosed for 6 weeks with metformin. Part C consists of Screening, Run-in (1 week), Stabilization (12 weeks), Treatment (6 weeks) and Follow-up periods.

Hypoglycemia is defined as symptoms consistent with hypoglycemia (e.g. dizziness, light-headedness, shakiness) which are confirmed by glucometer measurement of complete blood count (CBG) or plasma glucose value of \<50 milligram per deciliter (mg/dL) for Part A or \<70 mg/dL for Parts B and C (when possible, CBG values were confirmed with a laboratory measurement). In situations when no glucose sample could be measured at the time of the event, the investigator, at his or her discretion, characterized an event as 'hypoglycemia' based on reported signs and symptoms alone. Healthy participant also had asymptomatic blood glucose values \<70 mg/dL as a physiological response to altered food intake (e.g., fasting).

Possible overall scores range from 1 to 7, with lower scores indicating a better quality of life with respect to GI symptoms and higher scores indicating a lower quality of life with respect to GI symptoms. Baseline was defined as the assessment done on Day -2. Change from Baseline was calculated by subtracting the Baseline value from the individual post-Baseline (Day 7, 14, 28 and 41) values. If either the Baseline or post-Baseline value was missing, the change from Baseline was set to be missing.
Time frame: Baseline (Day -2) up to Day 41
Change From Baseline in In-clinic Body Weight During the Double-blind Treatment Period of Part B and C
During the assessment of body weight in the unit, the participant wore lightweight indoor clothing and removed shoes. The assessments were done pre-dose at Day -1, Day 1, Day 7, Day 14, Day 28, Day 42 and Day 43. Baseline value was defined as the average of Day -1 and Day 1 values. Change from Baseline was calculated by subtracting the Baseline value from the individual post-Baseline (Day 7, Day 14, Day 28 and Day 42) values. If either the Baseline or post-Baseline value was missing, the change from Baseline was set to be missing. Day 42 value was the average of Day 42 and Day 43 values.
Time frame: Baseline (Day -1 and Day 1) up to Day 42
Percent Change From Baseline in In-clinic Body Weight During the Double-blind Treatment Period of Part B and C
During the assessment of body weight in the unit, the participant wore lightweight indoor clothing and removed shoes. The assessments were done pre-dose at Day -1, Day 1, Day 7, Day 14, Day 28, Day 42 and Day 43. Baseline value was defined as the average of Day -1 and Day 1 values. Change from Baseline was calculated by subtracting the Baseline value from the individual post-Baseline (Day 7, Day 14, Day 28 and Day 42) values. Percent change was calculated by multiplying the change from Baseline value with 100. If either the Baseline or post-Baseline value was missing, the change from Baseline was set to be missing. Day 42 value was the average of Day 42 and Day 43 values.

Change From Baseline in Weighted Mean Glucose Area Under the Curves From Time 0 to 24 Hours (AUC [0-24 Hours]) During the Double-blind Treatment Period of Part B and C
AUC was calculated using the linear trapezoid method that is the sum of the areas between each chronological pair of assessments at the time points (at Day -1 and Day 42). The weighted mean was then calculated by dividing the AUC by the length of the time interval over which it was calculated. Baseline was defined as the assessment done on Day -1. Change from Baseline was calculated by subtracting the Baseline (Day -1) values from the post-Baseline value (Day 42). Data is reported for weighted mean glucose AUC (0-4 hour) post-breakfast and AUC (0-24 hour) post-breakfast. Adjusted mean is reported as least square (LS) mean.
Time frame: Baseline (Day -1) and Day 42
Change From Baseline in Fasting Glucose During the Double-blind Treatment Period of Part B and C
Baseline was defined as the assessment done on Day -1. Change from Baseline was calculated by subtracting the Baseline (Day -1) values from the post-Baseline value (Day 42). Adjusted mean is reported as LS mean.

Change From Baseline in Fasting Insulin and Weighted Mean Insulin AUC (0-4 Hour) and AUC (0-24 Hour) During the Double-blind Treatment Period of Part B and C
Two fasting samples 5 minutes apart were taken for insulin. Baseline insulin level was the average of the 2 fasting samples. For insulin weighted mean AUC (0-4 hour) and weighted mean AUC (0-24 hour) was calculated for Baseline (Day -1) and end of treatment (Day 42). AUC was calculated using the linear trapezoid method that is the sum of the areas between each chronological pair of assessments at the time points (at Day -1 and Day 42). The weighted mean was then calculated by dividing the AUC by the length of the time interval over which it was calculated. Baseline was defined as the assessment done on Day -1. Change from Baseline was calculated by subtracting the Baseline (Day -1) values from the post-Baseline value (Day 42). Data is reported for weighted mean insulin AUC (0-4 hour) post-breakfast and AUC (0-24 hour) post-breakfast.
Time frame: Baseline (Day -1) and Day 42
Change From Baseline in Glycated Hemoglobin (HbA1c) During the Double-blind Treatment Period of Part B and C

Change From Baseline in Homeostasis Model of Assessment-Insulin Resistance (HOMA-IR]) During the Double-blind Treatment Period of Part B and C
HOMA-IR was calculated from the Day -1 and Day 42 fasting glucose and insulin values using dataset generated from the HOMA-2 model. It contained the estimates for HOMA-% insulin sensitivity (S) for pairs of fasting glucose and fasting insulin values. Study data was merged with the HOMA dataset by glucose and insulin. HOMA-IR was calculated as 100/HOMA-%S. HOMA-IR was not determined for any values outside the ranges of plasma glucose 3.5 to 25.0 mmol/L (63 - 450 mg/dL) and plasma insulin 20 to 400 pmol/L. Baseline was defined as the assessment done on Day -1. Change from Baseline was calculated by subtracting the Baseline (Day -1) values from the post-Baseline value (Day 42). Data for Part C of the study was not collected because fasting glucose and insulin were not available at the specified time points.
Time frame: Baseline (Day -1) and Day 42
Change From Baseline in Matsuda Index During the Double Blind-treatment Period of Part B and C
The matsuda index was calculated from the Day -1 and Day 42 glucose and insulin results as 10,000 divided by (fasting plasma glucose x fasting plasma insulin x mean glucose at 0-2 hour post-dose x mean insulin at 0-2 hour post dose)\^1/2, where glucose was measured in mmol/L and insulin in pmol/L. Baseline was defined as the assessment done on Day -1. Change from Baseline was calculated by subtracting the Baseline (Day -1) values from the post-Baseline value (Day 42). Data for Part C of the study was not collected because fasting glucose and insulin were not available at the specified time points.
Time frame: Baseline (Day -1) and Day 42
Change From Baseline in Fasting Plasma Glucose (Safety Laboratory) Values During the Double-blind Treatment Period of Part B and C
